MASSACHUSETTS, A CORPORATION OF CONFECTIONERY-COATINQ MACHINE.

Application filed Ma 26, 1919. Serial No. 299,824.

To all whom it may concern:

Be it known that I, ALONZO L'INTON BAUS- MAN, a citizen of the United States of America, residing at Chicopee, in the county of Hampden and State of Massachusetts, have invented certaln new and useful Improvements" in Confectionery-Coating Machines, of which the following is a specification.

This invention relates to improvements in confectionery coating machines, and p'articularly to machines wherein the chocolate,

or other coating, is applied in a liquid state to the goods and the latter are then passed from one conveying, means to an-.

other while the coating is stillsoft,

In machines of this type, there'is a, tend I vided for eliminatin the disfiguring tails,

is disclosed in U. Letters Patent No. 1,302,205, granted A vention of Antonio agliuca.

-The present invention is directed to im' provements in the tail removing means dis- As disclosed in this patent, the tail removing means desirably takes the form of a roll located between the conveyer of the coating machine and the delivery conveyor. The former conveyer is located within the casing of the coating machine and such casing is heated, while the latter conveyer is located outside the casing and commonly conveys the goods to a cold room. At any rate, there is a substantial difference of temperature between the interior and exterior of the casing so that the coatings on the goodswill be hardened. The tail removing roll described, preferably, turns inthe direction of travel of the conveyers and the tails removed from the goods are carried by the roll to a scraper. Due, to the direction of rotation of the roll the coating material thereon is adjacent the exterior of the casing and thus subjected to a lower temperature.

geal the coating on the scraper, particularly when the cold room is employed for the outer surface of the scraper is exposed to the blast of cold air lssuin'g from such room.

Specification of Letters Patent.

The congelation of the coating on the scraper leads to a piling up of frozen coating materlal thereon, which, if allowed to continue may eventually clog or seriously interfere with the d'csired operation of the machine.

According to this invention, there is interposed between the tail removing element and the scraper, a member which moves in an opposite direction to said element for the'pur'poseof conveying the coating material on the element to the scraper and so conveying the material that it is exposed to the heated interior rather than to the colder exterior 'of the casing of the coating machine.

Other objects and advantages will appear 1n the following description and in the illustrative embodiment of the invention, vin

which s Figure 1 is a fragmentary elevational view, partly in section, of a coating machine embodying the invention;

Fig. 2 is an enlarged fragmentary view showing the means for removing the disfiguring ails from the coated confections; F 1g. 3 IS an enlarged fragmentary elevational .view showing the driving devices for said means; and H Figs. 4, 5, and 6 are diagrammatical views illustrative of the operation of the tail removing ineans.

Referring to these drawings: A represents the casing of a confectionery coating ma chine, which may be of any suitable type and a full disclosu1'e'-of-one suitable type will be found in U. Letters Patent No. 735,890, granted Au ust 11, 1903, on an'i'n: vention of E. P. F. l\ agniez. The casing A is heated by suitable means, exemplified in part by the" heating coils b. WVithin the casing is the usual endless conveyer 0, which carries the coated confections and which is usually of the wire belt type to permit exinto a region of lower temperature, such for example as the cold room C.

The conveyer ,0 is driven in the usual manner and its upper lap of travel maintained in a horizontal plane by means exemnee-i alified in part by the shaft 6 and member 7'. onveyer travels in the direction of the arrow, to carry the confections to belt d, and returns about a roll 9 toreceive other con-. fections. Excess coating 'material dripping from the conveyer c is received upon a pan h and flows back to the supply tank in casing A in the usual manner.'

latter is connected by gearing 0 to drive a horizontal shaft p, which, by means of the wormg and worm gear 1, drives roll j. v

The adjacent ends of the conveyers 0 and d are arranged in close proximity to effect the transfer of the coated confections from one to the other. Located in the space between such ends of the conveyers, is a roll 10, by means of which the disfiguring tails are removed from the coated confections, as fully set forth in the first-named patent. This roll is so disposed that its upper pe-a riphery lies substantially flush with the conveying surface of conveyers c .and d, and

referably slightly below such surface. 011.10 is driven, preferably in the direction of the conveyers 0 and d, by a chain 11 and suitable sprockets from the described shaft e, which is a driven shaft of the usual coating machine. I

The roll -10 is rotatably supported at its ends by two :spaced brackets 12 which are attached, as indicated'in Fig. 2, to the easing AI Also journaled in brackets 12 and below roll 10 'is a second roll 13, which is driven in an opposite direction from roll 10 :by intermeshing gears 14 (Fig. 3). Rolls 10 and 13 contact with each other and such coating material as is removed. from-the confections by roll 10 is wiped therefrom by, and transferred to, roll 13. Associated with the latter is a scraper 15, the ends of which are'suitably attached to lugs 16, provided on the brackets 12 described.

It is to be noted that the mechanism for removing the disfiguring tails from the confections, which mechanism includes rolls l0 and 13 and scraper 15 are all carried by the two bracketsl2, which may readily be attached to the frame of any coating chine. Thus, the invention, among other things, provides an attachment which is applicable to any standard-coating machine without necessitating alterations in the standard equipment." i

In operation, the coated confections 8, carried by conveyer ,0, pass therefrom, over the roll 10, to the 'conveyer d. As each such accumulations of coating material confection 8 leaves conveyer 0, atail 4' will be formed upon it, as shown in Fig. l, and. on further movement of the confection, the tail b will break away from the end of the conveyer 0 and drop upon the upwardly turning surface of roll 10, as shown in Fig. 5. This surface is a clean surface, since any accumulations thereon have been removed by roll 13. Accordingly, the tail 10 will adhere to the bare roll 10 and, by its subsequentrotation, the tail will be swept oil the end of the confection or reworked under .the confection. all as more fully outlined in the first-named patent.

It is to be noted that the roll 13 conveys g0 as are removed from roll 10, away .from the exterior ofvcasing A and toward the heated interior thereof. Moreover, the accumulations onroll 13 "are lodged on that side of the scraper 15, which exposed to the heated interior of the casing A, rather than to the colder exterior thereof. With roll 10 rotating in, the illustrated direction, and the scraper 15 engaged directly with it, the coating material removed from roll, 10 would lodge on the outer surface of the scraper and thereby be exposed to the cold air from the cold room C, whereby the coating material would freeze to the scraper and pile up into such an accumulation as to seriously interfere with the desired operationof the machine. With the interposed roll 13, this difiiculty is eliminated and the coating material lodging on scraper 15 may flow therefrom and, even should such material not flow readily from the scraper, it will be'removed by the conveyor 0 before any serious accumulation canpossibly occur.

he invention has been disclosed herein,

in an embodiment at present preferred, for the purposes of,ill ustration, but the scope of the invention is defined by the appended claims rather than by the foregoing description.
